RESEARCH TOPICS
One of the main themes of my current research activity is the functional renormalization group (FRG) and its applications to the study of QFTs. I exploit this approach to study the phase diagram of QCD making use of some effective models, specifically O(N)-symmetric model and the quark-meson model. I exploit the fact that the FRG flow equations for these models can be cast into the form of advection-diffusion equations, therefore making them solvable via hydrodynamic algorithms.
I also focus on the NJL model as an effective description of low energy QCD at high densities. Within the framework of this model, I study the impact of the coupling of axions to color superconducting matter.

Il programma di ricerca si concentrerà sull'utilizzo del Gruppo di Rinormalizzazione Funzionale (FRG) per lo studio delle transizioni di fase nella Cromodinamica Quantistica calda e densa (QCD). Il candidato prescelto implementerà i codici numerici necessari per risolvere le equazioni del flusso FRG a potenziale chimico e temperatura finiti, all'interno di modelli efficaci che catturano gli aspetti essenziali dell'interazione QCD. La ricerca si concentrerà sullo studio della linea critica nel diagramma di stato QCD, inclusa la temperatura e il potenziale chimico barionico. Successivamente il candidato estenderà la ricerca al caso dei mezzi anisotropi. Un'ulteriore estensione includerà l'accoppiamento dei quark densi all'assione QCD. Infine, i relativi codici saranno resi pubblici, secondo le linee guida del progetto.
